Hot air “FAULT” light illuminates on the air conditioning panel:

In case of Air Conditioning System Controller dual lane failure:

During normal flight the Avionics Ventilation System controls the temperature of the cooling air by:

The RAM AIR switch should be used:

The pack flow control valve closes automatically in case of:

Trim air valve failure

There are how many trim air valves?

During landing run, packs ram air inlet flaps open when the speed is less than:

When APU is supplying the Packs, the air conditioning system controller sends a demand signal to increase air flow when a zone temperature cannot be satisfied:

The ditching switch when selected ON sends a closure signal to:

In flight, with cabin pressure controller 1 in use, if it fails:

In normal operation, pressurization is:

The outflow valve is powered by:

During ground function operation, the outflow valve is:

To see the position of the outflow valve, it is necessary to call ECAM:

Two identical, independent, automatic digital pressurization controllers are used for system control:

Which controller generates excess cabin altitude and pressure outputs for ECAM indication in manual mode:

When Ram Air pb is set to ON, the outflow valve will open 50% when delta P is:

The purpose of the safety valves is to avoid:

The safety valves are operated:

When landing elevation is set to AUTO, the landing elevation is sent to the controller from:

When Mode SEL is set to MANUAL, the outflow valve is controlled by signals sent via controller 1 or 2:

On ECAM CAB PRESS page, the outflow valve indicator changes to amber if:

On ECAM CAB PRESS page, the safety valve indication changes to amber if:

On ECAM CAB PRESS page the cabin altitude indication changes to red, when the cabin altitude is:

Following a SYS 1 fault:

Cabin pressurization starts at:

The safety valves open at:

In automatic mode, cabin pressurization is optimized by using information from:
